Sorry to not include adequate information the first time. We are going
through a router at present (Linksys).
What I'm figuring we might need is simply a file/print server. Something
like one of the entry levels described here:

In general, one of the entry servers should have plenty of HP for your
needs. SATA drives are needed (or SCSI... less popular these days).
As Kerry suggested, you might want to pay a local consultant to set it
up for you with user accounts, basic file security, backup strategy,
etc.
I highly recommend having two drives, one for the system/OS, one for
the data. You can do this physically (two hard drives) or logically
(two partitions). It greatly simplifies security and backup.
RAID is nice if you can afford to have someone set it up (via a second
physical drive). RAID creates data storage redundancy on the fly. So,
the odds of losing anything, even with a drive crash, are low.
All of this storage talk ties into one important business concept that
most any of the "system consultants" you bring in are going to miss
since 99.9$ of them are hardware/software consultants, not business
consultants. They fail to consider are two key questions. The first
one is backup - how often, what type (incremental or full), turnover
strategy, and off site storage strategy. The key aspect they almost
always miss: the emergency scenario (i.e. what are you going to do
with the backups if the server goes down). As an example, I used to
go into a lot of businesses that had tape backup of their data. Their
key problem was that they only had a tape drive on one machine, the
server that just went down. Doh.
A second issue that they all miss is whether or not you *need* RAID or
some other backup strategy based on your business systems. For
example, is you are like a bank and all your transactions are written
on paper in addition to being entered into a system, then if the
server went down you could start from last night's off site backup
and rebuild the transactions one by one. Laborious, but it is a worst
case situation. On the other hand, if you take in transactions or do
work during the day that is only on the computer and only on one place
in the computer, then some sort of RAID is probably called for.
Consider all that.
We also want the ability to access files online from outside the office.
Talk to the consultant. If this is financial data, then you need some
sort of VPN solution. FYI- the system horsepower requirements may
increase if you are going to support multiple employees remotely
logged into the server.
